Despite its small size, Greece has a varied climate. Most of the country, including all coastal areas, enjoys the so-called Mediterranean climate. Weather in Greece is almost identical to much of California’s. Summers are hot and dry with a 8 month period of near-constant sunshine generally from Mars until November.
The remainder of the year is characterized by a relatively cold, rainy period which generally starts sometime in November and lasts until mid March. Keep in mind that with 80% of its territory being mountainous, many visitors are surprised to discover that there are high mountains like the Alps and it snows in the winter – a lot more in the north of the country.

Sporadic rains do occur during the dry season, but they tend to be rare, quick showers. The country’s Ionian Coast and Ionian Islands tend to receive more annual precipitation than the rest of the country. The islands in the southern Aegean and parts of the southeastern mainland are the driest areas of the country.
